LG CNS said on 2 November 2026 that it had completed a 30-megawatt AI data centre in Jakarta and was preparing an expansion that could take its total power capacity to 400 MW, Yonhap reported. The LG Group IT affiliate built the facility for KMG, a venture between Indonesia’s Sinar Mas Group and Korea Investment Real Asset Management. A completion ceremony took place in Jakarta on 1 November, The Korea Times reported.
Key points
- LG CNS said it secured customers for the Jakarta facility’s full capacity before construction finished.
- Chosun valued the construction project at 100 billion Korean won.
- The first phase uses air cooling; LG CNS plans liquid cooling in later phases.
- LG CNS is designing an expansion to 400 MW and plans to pursue other Asia-Pacific markets.
KMG commissioned the Jakarta project in 2025
KMG commissioned the project in 2025. Korea Investment Real Asset Management is a Korean alternative asset manager. LG CNS said it had secured customers for the centre’s full capacity before construction ended, The Korea Times reported. That customer commitment accompanied a completed facility rather than a proposal for one.
The Jakarta construction project was worth 100 billion Korean won, Chosun reported on 30 October, when it was still under construction. At that point, completion was scheduled for the fourth quarter of 2026. LG CNS has used a design-build-operate model for data centres since 2019, combining responsibility for their planning, construction and operation.
LG CNS described Jakarta as its first overseas AI data centre project for a local client, Yonhap reported. The facility is designed for high-performance computing using next-generation graphics processing units. For LG CNS, the completed project extends its data-centre work beyond South Korea with a client commission and capacity customers already in place.
LG affiliates supply Jakarta cooling and batteries
LG Electronics supplied the facility’s air-conditioning systems and LG Energy Solution supplied its batteries. LG CNS provided the design, build and operate work. The arrangement brings equipment and construction services from three LG affiliates into the Jakarta project.
The first phase cools servers with air. LG CNS plans to introduce liquid cooling in subsequent phases to accommodate denser AI server installations. The installed electrical system can deliver more than 300 kilowatts to each rack — about 60 times the power required by a typical data-centre rack. The facility also has backup power systems intended to keep it operating if its primary supply is disrupted.
The Jakarta project uses prefabricated modules, with major equipment manufactured before assembly on site, The Asia Business Daily reported. That approach is intended to shorten on-site construction and allow equipment and capacity to be adjusted to demand. The publication described the rack power system as capable of supplying 300 kilowatts per rack.
LG CNS designs a 400 MW expansion
LG CNS is designing a further phase that would take Jakarta’s total power capacity to 400 MW upon completion, The Korea Times reported. The company also plans to pursue AI data-centre business in Malaysia, Thailand, Vietnam, the Philippines and Japan. Yonhap listed Malaysia, Thailand, Vietnam and Japan among its planned markets.
Beyond building data centres, LG CNS plans subscription-based access to GPUs and liquid-cooling infrastructure, Yonhap reported. In September, the company unveiled prefabricated modular data centres based on Nvidia’s Vera Rubin platform, Chosun reported. The modules are designed to arrive on site with computing, power and cooling equipment already assembled.
LG CNS has also signed an agreement with KDDI to pursue AI projects across Asia-Pacific, AI Affairs previously reported. Other South Korean companies are pursuing data-centre work in the region through earlier-stage arrangements. SK Telecom and SK Innovation signed a memorandum with Vietnam’s Nghe An Province in April 2026 to explore a data centre and related power infrastructure, The Asia Business Daily reported.
Samsung C&T signed a memorandum with Vietnam’s CMC Technology Group in August 2025 for a data-centre project in Ho Chi Minh City valued at $1 billion, The Asia Business Daily reported.
